Foo'rAnJUsTMENT Fon 4CABIN N N 2,418,236 f `Bernard Schramka, Chicago,` IIL, .assignor to De VryuCorporation, Chicago, Ill.,-a `corporation Vof Illinois application December 7, 1945,1seria1 Nofcasnea Thisinvention relates to .certain new and` useful improvements in .foot `adjustment for cabinets. The invention is particularlyadaptable Vfor use in connection with motion picture projecting machines where it is desirable, for `properly locating v 2 cnims. (c1. 45p-139,)

This adjustable foot I4 comprises a mounting plate I5 secured to a cabinet portion I8* :by means ofsuitable screws IB. `This-mounting plate.` I5- has `a recessed portionY I1, and positioned in this a picture upon a screen to have the front portion l of .the cabinet of Vthe machine elevated at the proper angle with respect Vto the horizontal. The apparatus for this purpose must be capable of being operated'in a simple and expeditious manner in Vorder toY properly adjust the cabinet with l respect tothe horizontal, and such adjustment should be accomplished by the Aemployn'ient of one hand, thus enabling the operator to firmly hold the cabinet in place b y the use of his other hand while making the adjustment. l

`.its a principal object -ofthis invention, it is Y sought to provide a mechanism which will accomplish the function of permitting expeditious and convenient 'adjustmentof the foot so as to elevate one; portion of the cabinet, and which will function to maintain thecabinet with its end portionelevated by virtue of the weight of the cabinet imposed upon the mechanism, all by means of an arrangement of parte which are simple, capable of easy assembly, and which will work in a most eicient and expeditious manner.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings showing the preferred form of construction, and in which:

Fig. 1 is a side elevational view of a cabinet showing my improved foot adjustment associated therewith;

Fig. 2 is an elevational view of the foot adjustment embodied in my invention;

Fig. 3 is a fragmentary rear elevational view of the same;

Fig. 4 is a fragmentary sectional detail viewV taken substantially on line 4-4 of Fig. 3.

The drawings illustrate the preferred form of construction by which the several objects of my thereof feet I2. The front portion I3 of the cabinet is supported by the adjustable foot I4 which constitutes the subject matter of my improve-V ments.

recessed portion I1 are the mounting flanges `I8, of a .brake housing I8, theranges I8 .being secured-to the mounting plate I 5 by suitable screws 2li. The housing I9 hasa unitary partition 2I which divides the housing into a rear compart-l ment 22 and a forward compartment `23.

A coupling is indicated at C, and this coupling comprises a shaft 24, rotatably carried by the housing I9, .and having thereon va pinion '25, the portions 26 of which are utilized to pin a release disc`21 on the shaft .24. The cylindrical wall' 28 of the housingl' is provided `Withvertical opene .ings29 through which projects a rack bar 30; the-teethSI of which mesh'withlthe teeth v32 of the pinion 25. Thelower end portion 3.6 of this raekbar 38 is connectedasat 31 to a transverse bar 38,"the opposite -ends of which carryfeet 39 similar to the feet I2.

`Ihe disc 21 provides a shoulder 48, and adapted to engage `this shoulder 48 is an inturned lug 4I formed as an integralpart of fa release plate 42.` This release plate 42 is formed as a part of the sleeve 43 of the coupling and telescopically receives the end 44 of the shaft 24. Pinned as at 45 to this stud shaft 44 is a hand wheel 48.

The release plate 42 opposite the lug 4I provides a second lug 41 which engages in a hook-shaped portion 48 formed inone end portion 49 of a brake band 58. This brake band 50 is adapted to have braking engagement with the brake lining 5I mounted against the cylindrical wall 52 of the housing I9. The opposite end portion 53 of the brake band 58 is secured as at 54 to the disc 21.

This brake band 50 is preferably formed of an elongated flat piece of spring material, and the arrangement is such that the weight of the cabinet transmitted to the shaft 24 will have a tendency to urge rotation of the shaft 24 in an anticlockwise direction as viewed in Fig. 3, but due to the fact that when the sha-ft 24 is rotated in this direction, the rotation therewith of the disc 21 will tend to bear the brake band against the brake lining, with the result that a braking effect will be brought about between the shaft 24 and the housing I 9, and consequently maintain the cabinet I0 from moving down from its tilted position such as shown in Fig.4 1. To elevate the forward portion I3 of the cabinet ID, the shaft 24 isrotated in a clockwise direction as viewed in Fig. 3-` This is accomplished by rotating the handle 46 in that direction., which rotation of the handle in turn rotates the coupling sleeve 43 so as to bear the lug 4I against the shoulder 40, thus imparting rotation to the disc 21, which disc when rotated ina clockwise direction as viewed in Fig. 3, will tend to drag the end portion 53 of the brake band therewith and relieve the braking pressure of the brake band upon 'the brake lining. 'To "lower the front end I3 of the cabinet l0, the handle is `rotated By this arrangement the cabinet isv ried by the housing and said coupling comprising .l a shaft and a coupling sleeve, a release disc on the shaft and arranged in the housing and prosaid sleeve for alternately engaging said shoulder.` -and said hook formation.= Y

2. A footfor a cabinet or the like comprising a member adapted for connection to a wall of from an elevated position to a,horizontal posi-1 tion. The arrangement affordsgeasy operation of the mechanism to raise or lower the cabinet;

and in this operation of raising or lowering the cabinet it requires but the use of-one hand of theoperator.

4While I .have illustrated and described the preferred form of construction f or carrying my invention into effect, this is'capable of Variation and `modification Without departing from the spirit of the invention. I, therefore, do not wish y,

to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims. i I

Having thus described my invention, what I claim as new and desire to protect byLetters Patent is: i 1'. Av foot for a a mountingmember adapted for connection to a.A wall of theY cabinet, a brake housing secured to said member, abrake band linsaid housing and adapted for braking engagement with awall cabinet or the like comprising thereof, means arranged in the housing for contracting said brake band from braking engagement with said housing wall, a foot, andrack and pinion connection between said foot and an element of said contracting means, said contractingmeans comprising a coupling rotatably carthe cabinet and having an opening formed therein, Vra brake housing secured to said member, a

shaft rotatably mounted in said housing, a foot, y

racknand pinion connectionbetween said foot and vsaid shaft, a brake band in said housing and adapted Vfor braking Aengagement with a wall thereof, means providing connection between one end: of said .brake'band and saidshaft including a shoulder, a stud shaft projecting. through said opening, and having independent rotationrelative, to said shaftffan'd having means adapted to engage said shoulder torotate'said shaft in a direction to relieve the pressure of .said brake band against saidwall,of said housing, means providing a connection between said stud shaft and the opposite end of 4saidbrake band to relieve the pressure of said ,brake bandagainst said wall of said housing when said stud'shaft is rotated in an opposite direction,.and a handle onVV said istudshaft for rotating the latter.
